fold/unfold a cone shape

I need to add some geomerty to this part in the flat position.
This is a circuit surface and the only circuit layout available is in the flat pattern.
IV2010 has the fold/unfold options which should allow me to place the circuit layout onto the unfolded part.
If I unfold this part and then refold it, it does not refold correctly.
I thought that it might be because it does not have a flat section in the bend but even adding a flat section does not help.
Am I doing something so far out of the sheet metal range that it's not possible?
Any help, advise or otherwise would be appreciated.

thanks
Ken

It appears to work correctly in both Folded and Flat Pattern
modes here. What error are you seeing?

If I just use the "Folded Model" and the "Flat Pattern" from the browser tree, it does work fine.
I need to add circuit traces to the flat pattern. IV2010 has a new feature "Unfold and Refold" that will let you add features to the unfolded part that will remain when refolded. When I use the "Unfold" command and then "Refold", the part does not go back to the orginal folded configuration. Even if I just "Unfold" and "Refold" without any alterations, it does not go back to the original form. I maybe asking for something that is not possible with a cone shape. I'm hoping that it is something I am doing wrong or need to approach it from another direction.

Thanks
Ken

Have you gone through the 8 steps in this portion of New
Features Workshop under Help?

Yes, I did go though that.
If I pick the end of the curve as my fixed surface and then pick the cone or curve as the bend, it unfolds or flattens as it should. If I pick the end and surface to unfold, it does not fold all the way back.
I thought maybe because I did not have a continued surface that was flat that could be the issue so I added a small flat surface from the end of the cone. The results were the same, it does not refold back the orginal shape.

Thanks

If I add a feature in the flat, this is what I
get.

If I do a unfold/refold, the result is the same.

What you you are showing is what I am getting too. The refold does not close the cone or loop back up.
It has a large gap instead of the small gap as in the original before the unfold.
Am I missing something or am I asking for something that the software cannot do?

Thanks

Not sure. I'll defer to Seth H. on this one.

There's definitely something amiss here; folks are
digging in and will post up soon with the results of their
investigation.

Hi Ken,

The issue you described has been logged as #1200183 in our database but I am not sure when a fix will become available.

This "clipping" effect after refold happens for cones with an angle > 180 degrees. So depending on your requirements, a possible workaround for refold of large angle cones could involve unfolding, modifying and refolding smaller angle cones separately. You could then join them afterwards (using mirror solid, perhaps).

Thanks,

I think I've found the solution.

when you revolve the surface of the cone, don't revolve 'FULL', revolve 359.5º
This will resolve the issue.. tell me it works or not! it worked on my machine, when i face similar problem
